Quint gram gamut @ffim IMPROVEMENT IN SPRING WAGONSt JOSEPH N. BYINGTON,OF STOCKTON, MINNESOTA.

Letters Patent 1V0. 59,961, dated November 27, 1866.

SPECIFICATION.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, JOSEPH N. BYINe'roN, of Stockton, in the county ofWinona, and State of Minnesota, have inventeda new and usefulImprovement in Lumber Wagon; and I do hereby declare that the followingis'a full, clear, and exact description thereof, which will enable thoseskilled in the art to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in whichFigure 1 is an end view of a wagon illustrating my improvement, therunning part and the side and endboards of the box being omitted.

Figure 2 is a side view of the same, partly in section through the line:v :r, fig. 1. I

Figure dis a detail sectional view of the same, taken through the line zz, fig. 1, showing the position of the springs when not in use. i

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish a means by which a lumberwagon used for drawing heavy, loads I may be readily changed into'aspring wagon,- for conveying people or light loads; and it consists,firstjin hinging the springs to the bottom of the wagon-box andconnecting them to the bolsters in such a way that, when not in use,they may be turned up out of the way, or readily removed; and,- second,in the combination and arrangement of the springs, cross-bars, links,bolts, and catches with each other, and with the bottomboards andbolsters of the wagon, as hereinafter more fully set forth. f

A and B are the bolsters, C are the stakes, D the bottom of thewagon-box, and E the reach, about the construction of which parts thereis nothing new. The half-elliptic springs F are bolted at their middleparts to the cross-pieces G. The cross-pieces G are hinged to the bottomD, as shown in the drawings, so that when not in use they may be turnedup along the under side of the bottom D, as shown in fig. 3, in whichposition they are held by the spring-catch H, or, by moving themlongitudinally, they may be readily detached from the said wagon-bottom.I are links, towhich the ends of the springs F are pivoted, and whichare pivoted to the ends of bolts J, to which they are secured by keys,as shown in figs. 1 and 2. The bolts J pass through the bolsters A andB, and should be of suflicient strength to sustain the weight of thewagon-box and load. The halfelliptic springs F may be replaced byelliptic springs, if desired; but in this case the middle part of thelower halves of the springs must be attached to another cross-bar, theends of which must be pivoted to the links I. By this arrangement of thesprings, where it is desired to carry heavy loads, the linksI can beslipped from i the bolts J, and the springs F turned up into theposition shown in fig. 3, or wholly removed. The weight of the load thenrests directly upon the bolsters A and B, and there is no danger ofbreaking the springs. But when the wagon is to be used for carrying'light loads, or for riding purposes, by placing the springs F in theposition shown in figs. 1 and 2, the vehicle will become an easy-ridingspring wagon.

I claim as new, and desire to secure by Letters Patent 1, Hinging thesprings F to the bottom, D, of the wagon, and connecting them to thesidesmf the bolsters A and B in such a manner that when not in use theymaybe turned up out of the way, substantially as herein described, andfor the purposes set forth., i

2. The combination and arrangement of .the springs F, cross-bars G,links I, bolts J, and catches H, with each other, and with the bottom,D, and bolsters, A and B, of the wagon, substantially as hereindescribed, and

for the purpose set forth.
